More often than not, these are people influenced by religious dogma and doctrine and not secular concerns. Indeed, most secular humanists, progressives and liberals in the U.S. oppose such policy. This isn't to say that the secularists necessarily have a better position; nor am I excluding the fact that there are secular conservatives (very few, however).
But the vast majority of those that approve things like "war on terror" will invoke discussions of "god's will" in the same breath.
I'm not against people having religious belief. But they shouldn't have this sort of domination in our government and national policy.
They? You mean atheists would be less self serving and promote self determination in the countries under current US foreign policy?
